UNITED STATES Lama CHARLES H. BOSENFIELD, OF SALT LAKE CITY, UTAH.

JAR WRENCH.

Application filed July 22, 1922. Serial No. 576,898.

To all whom it may concern:

Be it known that I, CHARLES H. ROSEN- FIELD, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented new and useful Improvements in Jar Wrenches, of which the following is a specification.

This invention relates to a device for removing and replacing tops on jars and the like, the general object of the invention being to provide an adjustable gripping member with means for adjusting the same by the handle of the device.

Another object of the invention relates to the specific means for rotatably connecting the handle with the jaw part.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim; I

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a side view of the device.

Figure 2 is a similar view with parts in section.

Figure 3 is a section on line 3-3 of Figure 1. v V

Figure 4 is a section on line H of Figure 2.

In these views 1 indicates a substantially the shank. This upper edge of the shank is curved and threaded, as shown at 5. A handle 6 is arranged on a bolt 7, the screw other the plate 8 will be projected or. retracted on the shoulder so that it can be made to engage a part of the jar top when the device is in-use and thus clamp the device to the top. This will permit the top to be turned to remove it from the jar or to tighten it thereon.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the severalparts, provided that such changes fall within the scope of the appended claim.

What I claim is A jar wrench comprising a member of semi-circular shape having a recess at its inner end, a U-shapedclip secured to this end of the member and forming a circular space with one edge of the member which is rounded, a part of the wall of said space being threaded, a handle, a bolt passing through the same and having its threaded part passing through the space and engaging the threads, a corrugated gripping plate movably connected with a reduced end of the threaded part of the bolt, said plate being located in the recess with one edge thereof engaging the wall of the recess.

In testimony whereof I aflix my signature.

CHARLES H. ROSENFIELD.
